At this point, we have 10 yes and 9 probably. Two more would put us at 12 yes and 9 probably. If the probablies are really yeses, that the number is 21 and we would start planning the session. 20 participants would put the cost in the $1,000 range (factoring in conference room costs. The size of the conference room would then be the key factor in how may total we can get. I personally think we can fit 30 in a room without issue.
